This might be covered in a FAQ posting, so I apologize if it is.

What transformation is best for converting a transfer function in a CONTROL
SYSTEM to the z-domain?  Right now I'm using the bilinear-z transform and
I'm converting a system that MATLAB says is stable, but when I actually 
implement the system on a DSP board, it is unstable.  Any help would be
greatly appreciated!
